Preheat oven to 425 degrees F.
Place salmon skin-side down on a lightly greased baking sheet, and season with some salt and pepper. Brush with olive oil, and bake it for 10-15 minutes.
Preheat your air fryer to 370 degrees F.
Once baked, discard the skin, and flake the salmon with a fork and add it to a large bowl. If it has any bones, remove them and discard.
Next, add to the salmon the rest of the ingredients, and mix them together using your hands, until well combined.
Use an ice cream scoop for portioning so each salmon patty is about the same size, and make into patties.
Place a piece of parchment round down inside the hot air fryer then carefully place each cake in the air fryer. Cook in batches if needed, don't overcrowd.
Cook in the air fryer for 8-10 minutes until the crust turns golden brown. Do not flip while cooking.
Remove from the air fryer and enjoy with your favorite sauce and extra lemon on top, if desired. Garnish with green onions.
